Eh. There was a movement not too long ago asking Libertarians to move to New Hampshire, one of the states that already advocates personal liberty and freedom and minimal government, and they sought to make it a Libertarian state.

Really, I don't think this is all that different. And really, if you think about it, it's actually a benefit for the rest of the nation. Think about gerrymandering; if you pile districts so that there's one district tilted overwhelmingly to one side, that means everywhere else is now tilted closer to the other side. Meaning, if there was a mass exodus there, everywhere else would be free of their influence, and politicians who leaned towards that population would be out of office.
